Softcover. Condition: Good. Unstated printing/date (intro mentions the next edition's release in 1978), trade paperback, the hinges are popped but solid, and the book has bumps with some creasing to the spine ends and cover corners, light creasing to the lower corner of the last several pages, sunning with reading creases to the spine and hinges, rubbing with smudging to the covers, and soiling to the front. Overall, a solid, Good copy.
